Background
Ethyl glucuronide (EtG) in hair has emerged as a useful biomarker for detecting alcohol abuse and monitoring abstinence. However, there is a need to establish a reliable cutoff value for the detection of chronic and excessive alcohol consumption. 相似文献3.

Introduction
Accurate quantification of tumour tracer uptake is essential for therapy monitoring by sequential PET imaging. In this study we investigated to what extent a reduction in administered activity, synonymous with an overall reduction in repeated patient exposure, compromised the accuracy of quantitative measures using time-of-flight PET/CT. 相似文献8.

Purpose
To facilitate effective learning, feedback on performance during arthroscopic training is essential. Less attention has been paid to feedback on monitoring safe handling of delicate tissues such as meniscus. The goal is to measure in vitro probing forces of menisci and compare them with a theoretical maximum probing force (TMPF). 相似文献9.

Objective
Quantification of tumour burden in oncology requires accurate and reproducible evaluation. The current standard is RECIST measurement with its inherent disadvantages. Volumetric analysis is an alternative for therapy monitoring. The aim of this study was to evaluate the feasibility of volumetric analysis of lymph node metastases using a software prototype in a follow-up setting. 相似文献10.

Purpose
The aim of this study was to explore the role of 18F-FDG PET/CT for monitoring treatment response in patients with primary inoperable (i.e. advanced) penile carcinoma treated with induction chemotherapy and to compare the metabolic tumour response with the radiological evaluation provided by CT imaging. 相似文献11.

Purpose
MRI coupled with the intravenous injection of ultrasmall superparamagnetic particles of iron oxides (USPIOs) is a promising tool for the study of neuroinflammation. Quantification of the approximate number of magnetically labelled macrophages may provide an effective and efficient method for monitoring inflammatory cells. The purpose of the present study was to characterise the relaxation properties of macrophages labelled with two types of USPIOs, at 4.7 T and 7 T. 相似文献12.

Purpose
The aim of this study was to assess the accuracy of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT to visualize lymph node metastases before the start of neoadjuvant chemotherapy and to determine how often the visualization is sufficiently prominent to allow monitoring of the axillary response. 相似文献13.

Objective
The guidelines for microdosing in clinical trials were published in Japan in 2008 following the guidelines of the European Medicines Agency and the Food and Drug Administration. They recommend utilizing accelerator mass spectrometry (AMS) and positron emission tomography as candidates for monitoring drug metabolites in preclinical studies. We correlate the two methods by measuring appropriately labeled tissue samples from various mouse organs using both AMS and gamma counter. 相似文献14.
Pediatric lymphoma: metabolic tumor burden as a quantitative index for treatment response evaluation
Objective
Metabolic tumor burden (MTB) incorporates the advantages of the existing indices: the metabolic volume of the lesion calculated by size-dependent thresholding on positron emission tomography–computed tomography (PET–CT) along with its aggressiveness as determined by standardized uptake value (SUV). This study was conducted to investigate whether MTB can be used as an objective index for monitoring therapy response in pediatric lymphoma. 相似文献15.

Purpose
18F-fluorodeoxyglucose (FDG) PET/CT has been widely used for staging, re-staging and for monitoring therapy-induced changes and response to therapy in patients with various types of cancer, but its utilization for gastric cancer has been limited. The purpose of this study was to evaluate the clinical role of FDG PET/CT in the detection of gastric cancer recurrence as compared with diagnostic CT and to assess the impact of FDG PET/CT results on patients’ treatment planning. 相似文献16.
Objective
MRI has recently been introduced as a promising method of monitoring the transplanted pancreatic islets labelled with superparamagnetic iron oxide (SPIO). However, the traditional T2* {\hbox{T}}_2^* -weighted approach frequently yields ambiguous results because of the negative contrast of the SPIO particles on the background of other body components. This obstacle could be overcome with the use of a novel method known as echo-dephased steady state free precession (SSFP), generating positive contrast in the presence of paramagnetic material. 相似文献17.

Purpose
Targeting of integrin ανβ3 with molecular imaging agents offers great potential in early detection and monitoring of tumour angiogenesis. Recently, an RGD (Arg-Gly-Asp) tracer, 99mTc-3P4-RGD2, with high affinity to integrin ανβ3 and in vivo tumour uptake was developed. In this study, we evaluate the feasibility of this novel radiotracer in the noninvasive differentiation of solitary pulmonary nodules (SPNs). 相似文献18.
Objective
To examine the criterion related validity of the sit-and-reach test (SR), toe touch test (TT), modified sit-and-reach test (MSR) and back-saver sit-and-reach test (BSSR) for estimating hamstring flexibility measured through the passive straight leg raise test (PSLR) in professional futsal players.Design
Correlation laboratory study.Setting
Controlled laboratory environment.Participants
One hundred and three futsal players (55 males age 26 ± 4 years, 48 females age 23 ± 5 years).Main outcome measures
Two trials of SR, TT, MSR, BSSR (left and right) and PSLR right and left (hamstring criterion measure) in a randomized order.Results
Regression analysis was performed to examine the association of SR, TT, MSR and BSSR with PSLR in both males and females separately. In males, only MSR test had moderate association criterion with PSLR (R2 = 0.57). In females, SR (R2 = 0.86), TT (R2 = 0.85), MSR (R2 = 0.53) and average BSSR (R2 = 0.82) were associated with PSLR.Conclusions
SR, TT, MSR and BSSR had moderate criterion related validity for estimating hamstring flexibility in female but not male professional futsal players. The authors recommend that researchers, clinicians, and physical therapists adopt one angular test as a measure of hamstring muscle length in futsal players. 相似文献19.
Introduction
The impact of resistance exercise on the growth of the vastus lateralis was assessed through interstitial microdialysis measurement of free Insulin-like Growth Factor-I at +3 h30, +4 h50 and +6 h after exercise in 4 healthy subjects.Results
We observed 3 h30 after exercise an interstitial increase in 3 over 4 subjects, and thereafter a progressive decrease. In the mean time, free or total plasma concentrations did not change.Conclusion
Resistance exercise seemed to induce an early increase of muscle interstitial free Insulin-like Growth Factor-I in order to initiate muscle growth by an autocrine – paracrine way. 相似文献20.
